. METALLIC WHEEL. v

4 v Specification of Letters Patent. Application filed June 22, 190a. Serial imaoaraa.

Patented Ju 26,1910.

To' all whom it may concern:

l 3e it known that L'Saiuonnsrnont, a citizen of the. United States, residing at Chicago, nois, have invented certain new and useful Improvements in Metallic Wheels, of which the following is a specification.

My invention relates to im rovements in wheels, and more particular y to metallic wheels adapted fornse on go-carts, cycles,

,readily receive a rubber tire.

- Other objects will; appear herleinafter.

W thFthese ob ects in view my invention consists in the novel "construction and ar- -rangement of parts which will be hereinafter fully described and more particularly pointed out in the appended claims.

My invention further consists in a modified form of wheel which possesses features in common with the My inventionwill more readily understood by reference to 'the accompanying drawin forming a part of this specificapzeferred form.

' tion an in which,

Figure l-is a side elevation of in 'imroved wheel in. i ts preferred form, Big. 2' is asection thereoftaken on line w-a: oi

-Fi'g. 1, Fig. 3' is la. detail section taken on the outer spokes and- 3 the inner s line -y of Fig. 1,.Fig. 4 is a detail side elevationvshowing. a port on ofthe outside of the inner rim portio'n, and Fig. 5 is a detail side elevation showing the inside of the outer'rim'portion.

Referringnow to the drawin s 1 desig nates the tubular hub. of the w eel, 2 the spokes 2 and the outer half 0 the rim 4,

'together with the hub sleeve 5 are struck body portion of I tubular form,

up from a singleblank of sheet metal, and the spokes 3,,the inner half of the rim 6, and the hub sleeves? are, similarly formed. The each spoke is pressed into'a the contiguous edges 8 o the spokes 2 being on [aim is r edges'8 of the spokes 3 being on the oaitsithe. thereoficausing the wheelto present a heater ap earance than if these oints were less'coiieea ed from view. Moreover spokes county of Cook, and State of Illiventioii,

okes. The

f described. the inside thereof, and

formed in this manner are stiff and strong,-

and their surfaces are such that the -same may be readily cleaned or painted.

The sleeves 5 and 7 are provided with inwardly extending flanges 9 and 10 respectively to engage the ends of the hub 1, which eflectually old the latter in position. The rim portions 4 and 6 are preferably provided with inwardly extending flanges 11 and 12 respectivelyio clench the sides of the rub.- ber tire 13, whereby the latter is held rigidly in posit-ion. I

In order to hold the rim portions 4 and '5 together when the wheel is assembled, abutting flanges 14 and715 are formed in said ortions respectively, the outer flanges l4 iaving projections 14' which are bent over the inner flan e 15 as shown in Fig. 2.

It will be "noted that the inner flange i5 is cut away at 16 so after the projections 14' are bent into osition, the ad acent surfaces as shown in Fig. 1 are flush, an exceptionally neat construction being the result. This construction alsp locks the rims against cireumferential sipping and the projections 14' constituting short portions of the are are easily bent. Various slight changes might be made in the. general form and arrangement of parts described without departing from my inand hence. I do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope as the appended claims.

Having lescribed my invention what I claim as new and desire to secure by Letters Patent is:

1. A metallic wheel comprising a cylindrical metallic hub; oppositely disposed sets of converging tubular spokes, each set being formed from a sheet of metal provided with means for engagingsaid hub; rimsections ion carried by the outer ends of. said spokesqf and abutting flanges on the inner ed es at said rim sections, one of said flan es eing provided with extendedsecurin over the other flange, said other ange being notched to receive said lips, substantiallv as 2. A metallic wheel drical metallic hub consisting of a continuous metallic tube; goppositely disposed sets.

i-ps bent.

comprising a 'cylin' i inwardl extending flange at itsouter end,

shallow outwardly extending sleeve at its center, said sleeve being 'providdwith an tightly tting over the corresponding end of said hub, rim sections carried by the outer ends of said spokes; and abutting flanges on the innen edges of said rim sections; the outer .of said 'flanges beingprovided with extend-- ing securing hps bent over the inner flange and of ,a length shorter thanthe distancebetween two spokes, said'inner flange being notched to receive said lips, substantially as described.

In testimony whereof I have signed my name to this specification in the. presence of 15 two subscribing witnesses. r
